Constructed from durable zinc alloy and reinforced with a satin nickel finish, the TEEHO TE018 Smart Door Knob integrates a keypad and app-based control into a single handle unit. Its solid metal housing resists corrosion and daily wear, while the smooth turning mechanism ensures reliable operation over repeated use. The lock employs an advanced electronic core that maintains stable performance under typical indoor conditions, supporting up to 20 user codes, one-time passcodes for guests, and remote sharing via the companion mobile application. The built-in auto-lock function can be customized with delay timers, adding convenience without compromising security. Installation follows a straightforward process that fits standard residential door preparations, requiring only a screwdriver and a few minutes to replace existing knobs on front doors, bedrooms, or rental properties. The keypad is backlit for low-light visibility and features a responsive tactile feedback, enhancing ease of use for all household members. Power is supplied by four AA batteries, with a low-battery indicator that prevents unexpected lockouts. The locking mechanism itself is designed for smooth engagement and disengagement, with a manual interior turn piece for egress at any time. The Bluetooth-enabled app allows users to grant temporary access, view entry logs, and adjust settings remotely within a limited range. The exterior keypad surface is treated to resist fingerprint smudges, maintaining a clean appearance over time. The overall build quality emphasizes longevity, with the latch and deadbolt components meeting common security standards for residential use. This model is particularly suitable for homeowners seeking a cost-effective upgrade to keyless entry, as well as landlords who need to manage access for multiple tenants without replacing physical keys. The satin nickel finish coordinates well with a variety of décor styles, from modern to traditional. While the lock prioritizes functionality over advanced smart home integrations, its core features—app control, code sharing, auto-lock, and easy installation—provide a reliable solution for daily entry needs. The product is designed to operate within a typical household environment and is not intended for high-security commercial applications. The code entry process is straightforward, with audible and visual feedback confirming each key press. The app interface is intuitive, allowing users to quickly add or delete codes and monitor usage. At its price point, the TEEHO TE018 offers a well-balanced set of features and solid construction, making it a practical choice for those looking to simplify home access without incurring significant expense. The absence of Wi-Fi connectivity means the lock focuses on core functionality rather than cloud-based features, keeping the operation simple and battery efficient.

This smart door knob delivers consistent performance for everyday use, combining security, convenience, and durability in an affordable package.
